Problems solved by technology

[0003] At present, in the existing data interaction methods, if the interconnection between two systems is to be realized, especially when the public Internet system wants to access a system with confidentiality requirements, it must go through a mechanism such as a transfer machine. The number of visits below is limited by factors such as the number of transit planes and the performance of transit planes.

[0040] see figure 1 , which is a schematic flowchart of a block chain-based data delivery method provided in this embodiment, the method includes the following steps:

[0041] S101: Receive a user access request and a user information uplink request sent by the first blockchain system.

[0042] In this embodiment, in order to ensure that the data exchanged between the two systems is safe, reliable, non-tamperable, and traceable while solving the difficulty of agile transformation for traditional large-scale Internet companies, it is first necessary to remove The traditional transfer machine uses blockchain technology to interact with the data between the two systems. To this end, it is necessary to construct respective blockchain systems (herein respectively defined as the first blockchain system and the second blockchain system) in the internal network and the external network. Among them, the first blockchain system refers to the blockchain system accessed through the Inte...

[0066] This embodiment will introduce a blockchain-based data interaction device. For related content, please refer to the above method embodiments.

[0067] see figure 2 , which is a schematic diagram of the composition of a blockchain-based data interaction device provided in this embodiment, the device includes:

[0068] The first receiving unit 201 is configured to receive a user access request and a user information uplink request sent by the first blockchain system;

[0069] The first generation unit 202 is configured to generate a hash value corresponding to the user information after the user information is successfully uploaded to the chain;

[0070] The verification unit 203 is configured to analyze the hash value through the second block chain system to obtain an analysis result, and verify whether the user information is qualified according to the analysis result;

[0071] The second generation unit 204 is configured to verify that the user information is qualif...

Abstract

The invention discloses a data interaction method and device based on a blockchain, and the method and the device can meet the confidentiality demands of a conventional large-scale Internet enterprise, also can meet the quick response demands under an agile development condition, and achieve the quick data interaction between two systems. The method comprises the following steps: firstly, receiving a user access request and a user information uplink request sent by a first blockchain system, then, after the user information is successfully linked; generating a hash value corresponding to the user information; then, the hash value is analyzed through a second block chain system; obtaining analytic results, verifying whether the user information is qualified according to the analysis result;and if yes, generating a first operation instruction according to the received access request and sending the first operation instruction to the user, so that the user operates according to the firstoperation instruction to obtain a second operation instruction, and then receiving the encrypted second operation instruction sent by the first blockchain system to realize data interaction between the two systems.

Description

technical field [0001] This application relates to the technical field of blockchain, and in particular to a blockchain-based cross-border payment method and device. Background technique [0002] Blockchain is essentially a distributed, multi-centralized chained data storage system, which has the characteristics of decentralization, programmable time series data, and security and credibility. With the help of the powerful computing power formed by the consensus algorithm such as the workload proof of each node in the distributed system, it can resist external attacks, ensure that the blockchain data cannot be tampered with, and ensure that the data is safe and reliable. [0003] At present, in the existing data interaction methods, if the interconnection between two systems is to be realized, especially when the public Internet system wants to access a system with confidentiality requirements, it must go through a mechanism such as a transfer machine. The number of visits u...
